Evaluating project maturity from data sources

ABSTRACT

Techniques are provided for performing automated operations to determine maturity of a specified project. Information is received regarding each of a plurality of artifacts associated with the project, such as project documentation, source code repositories, and a tracked issue database for the project. A data sufficiency level associated with each provided artifact is determined, and each artifact is provided to one or more of multiple analysis engines. The analysis engines are executed to produce one or more weighted feature vectors for each of the artifacts associated with the specified project, and input to a prediction engine in order to provide a maturity rating for the project based on the weighted feature vectors.

BACKGROUND

The present invention relates to evaluating project maturity, and more specifically to evaluating the maturity level of a project from data sources.

The maturity level of a project such as a network-accessible service or software library may be described as the extent to which it is usable by parties other than the developer of that project without errors or complications. Typically, identifying one or more existing projects that are available for a particular task may be simpler than determining whether a particular one of those existing projects is mature (and therefore reliable), or to determine which of multiple projects has a greater maturity level.

SUMMARY

According to one or more embodiments, a method implemented by one or more computing systems configured to evaluate maturity of a project comprises receiving information regarding a plurality of artifacts associated with a project. The method further comprises, for each of at least some of the plurality of artifacts, determining a data sufficiency level associated with the artifact, identifying one or more of multiple analysis engines with which to analyze the artifact, and generating one or more weighted feature vectors for the artifact based at least in part on analyzing the artifact by the identified one or more analysis engines. The method further comprises providing, based at least in part on the weighted feature vectors, a predicted maturity rating of the project.

Other embodiments of the present invention include a computer program product and system.

Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. For a better understanding of the invention with the advantages and the features, refer to the description and to the drawings.

DETAILED DESCRIPTION

In order to evaluate a current maturity level of a project, various artifacts associated with the project (e.g., project documentation, one or more source code repositories associated with the project, an issue tracking system associated with the project) can be evaluated. Such evaluation provides insight as to how active the project is, how competent the project team is, what the project development plan (or “roadmap”) is, and how reliable the project may be as a third-party asset.

As used herein, the term “project” refers to any executable facility available for use by a party or entity other than that which created the executable facility, such as a network-accessible service or software library. The term “artifact,” also as used herein, may refer to any content or portion of content associated with a project. Non-exclusive examples of such artifacts include project documentation, source code repositories associated with a project, issue tracking systems associated with a project, user and/or developer forums associated with a project, or similar content. Artifacts associated with a project may be structured (e.g., a number of defects and commits, reports, team, work assignments, and other similar artifacts) or unstructured (descriptions associated with defects and work assignment, feedback, documentation, and similar artifacts).

Techniques described herein may be utilized in order to automatically evaluate a maturity level of a project by determining a project maturity rating based at least in part on information captured in various artifacts (structured and unstructured) associated with the project. Higher maturity ratings are typically associated with those projects which are frequently updated and are associated with active developers and developer artifacts such as issue tracking systems.

In various embodiments of techniques described herein, a project maturity assessment (PMA) system takes as input various artifacts about a project and maps these artifacts as input to a multitude of distinct analysis engines. Additional information on the project is collected by sourcing data from various portals (which may include, as non-limiting examples: web search, enterprise search, discussion forums, etc.).

In at least some embodiments, each of the multiple analysis engines may perform an assessment of the project with respect to a particular feature set, and output a weighted feature vector which reflects an extent to which that particular feature set is present in the project. Each weighted feature vector is provided as input to a prediction engine of the PMA system in order to output a prediction of project maturity, which in one or more embodiments includes with a confidence score regarding the predicted project maturity. In certain embodiments, the PMA system may include a classification engine to determine, for each of at least some of the multiple analysis engines, those artifacts to be used as input. The classification engine may utilize one or more combinations of a machine learning process and rule engine. The PMA system may continuously modify the classification engine based on input or feedback (human assessment) about a project over time.

FIG. 1 illustrates a block diagram of a networked computing system 100 suitable for use as an embodiment of a PMA system in accordance with the present invention. The methods described herein can be performed or otherwise implemented via hardware, software (e.g., firmware), or a combination thereof. In an exemplary embodiment, methods described herein can be implemented (at least in part) part by a microprocessor of a special or general-purpose digital computer, such as a personal computer, workstation, minicomputer, or mainframe computer. As depicted computing system 100 includes computer 105.

In the illustrated embodiment of FIG. 1, the computer 105 includes a processor 110, a data source manager 111, a project domain analyzer 112, analysis engines 113, a prediction engine 114, a memory 115 coupled to a memory controller 120, internal storage 125, and one or more input and/or output (I/O) devices 150 that are communicatively coupled to the computer 105 via a local input/output controller 135, which in the illustrated embodiment is further communicatively coupled to external storage 130. Data source manager 111 is configured to receive one or more artifacts as input elements. The operation of data source manager 111, project domain analyzer 112, analysis engines 113, and prediction engine 114 are described in further detail below with respect to FIG. 2. The input/output controller 135 may include one or more buses or other wired or wireless connections, as is known in the art. The input/output controller 135 may further include additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to facilitate communications. Further, the local interface may include address, control, and/or data connections to facilitate appropriate communications among the aforementioned components.

Also in the illustrated embodiment, the processor 110 is a hardware device for executing instructions stored in memory 115. The processor 110 can be any custom made or commercially available processor, a central processing unit (CPU), one of several processors associated with the general-purpose computer 105, a semiconductor based microprocessor (in the form of a microchip or chip set), a macroprocessor, or generally any device for executing instructions.

The memory 115 can include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, erasable programmable read only memory (EPROM), electronically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), tape, compact disc read only memory (CD-ROM), disk, diskette, cartridge, cassette or the like, etc.). Moreover, the memory 115 may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory 115 can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor 110.

The instructions in the memory 115 may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of FIG. 1, the instructions in the memory 115 include a suitable operating system (OS) 145. The operating system 145 typically controls the execution of other computer programs and may, among other capabilities, provide scheduling, input-output control, file and data management, memory management, and communication control and related services.

In an exemplary embodiment, I/O devices 150 may include, as non-limiting examples, a keyboard, mouse, printer, scanner, microphone, a network interface card (NIC) or modulator/demodulator (for accessing other files, devices, systems, or a network), a radio frequency (RF) or other transceiver, a telephonic interface, a bridge, a router, and other peripherals communicatively coupled to the computer 105 via input/output controller 135. In the depicted embodiment, the computing system 100 further includes a display controller 160 coupled to a display 165, and a network interface 170 communicatively coupled to a network 175. In the depicted embodiment, one or more client computing devices 190 are communicatively coupled to the network 175, such as client computing devices associated with users who provide indications of particular artifacts associated with a specified project in order to receive from the PMA system a project maturity rating for the specified project.

The network 175 may be an IP-based network for communication between computer 105 and any external server, client and the like via a broadband or other network connection. The network 175 transmits and receives data between the computer 105 and external systems. In an exemplary embodiment, the network 175 may be a managed IP network administered by a service provider. The network 175 may be implemented in a wireless fashion, e.g., using wireless protocols and technologies, such as WiFi, WiMax, etc. The network 175 may also be a packet-switched network such as a local area network, wide area network, metropolitan area network, Internet network, or other similar type of network environment. The network 175 may be a fixed wireless network, a wireless local area network (LAN), a wireless wide area network (WAN) a personal area network (PAN), a virtual private network (VPN), intranet or other suitable network system and includes equipment for receiving and transmitting signals.

In at least some embodiments, the memory 115 may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of routines that initialize and test hardware at startup, initiate execution of the OS 145, and support the transfer of data among the hardware devices. The BIOS is typically stored in ROM so that the BIOS may be executed when the computer 105 is activated. When the computer 105 is in operation, the processor 110 is configured to execute instructions stored within the memory 115, to communicate data to and from the memory 115, and to generally control operations of the computer 105 pursuant to the instructions. In some embodiments, data source manager 111, project domain analyzer 112, analysis engines 113, and prediction engine 114 can be embodied as software instructions and stored in memory 115.

FIG. 2 depicts an exemplary architectural diagram of a PMA system 200 in accordance with an embodiment of the present invention. In the depicted embodiment, the PMA system includes a data source manager 210, a project domain analyzer 220, analysis engines 230, and a prediction engine 240. In some embodiments, data source manager 210, project domain analyzer 220, analysis engines 230, and prediction engine 240 correspond to data source manager 111, project domain analyzer 112, analysis engines 113, and prediction engine 114, illustrated in FIG. 1, respectively. In addition, FIG. 2 illustrates a variety of input artifacts 205 a-205 d associated with a project, as well as an output 250 that includes a project maturity score and confidence score.

The data source manager 210 is responsible for managing information regarding various artifacts or input elements that may be used by the PMA system to predict a project's maturity. In particular, the data source manager receives information indicative of project artifacts that are associated with a specified project. In the depicted embodiment, the project artifacts include source code repository artifacts 205 a, web (or intranet) artifacts 205 b, domain knowledge artifacts 205 c, and project/team assessment artifacts 205 d (such as assessments of one or more other projects related to the particular project to be assessed by the PMA system). In the depicted embodiment, the data source manager 210 includes a data sufficiency analyzer 212, a data source retriever 214, and an analysis selector 216.

The data sufficiency analyzer 212 determines if the artifacts that are provided to the PMA system are sufficient to predict the associated project's maturity. During the training phase, the data sufficiency analyzer learns (based on rules or using machine learning) particular data sufficiency criteria; in general, the higher the maturity of a project, the more information may be necessary to understand various aspects associated with a project. In addition, in at least some embodiments the data sufficiency analyzer may provide one or more indications of any gaps that may be present in the artifacts associated with a specified project. For example, if for the specified project there is no input regarding feedback from a user community, such deficiency may be highlighted by the data sufficiency analyzer 212 as a gap.

The data source retriever 214 augments the input of project artifacts 205 a-205 d with additional information that may be retrieved by the PMA system from various internal and external portals. For example, team member reputation or user feedback regarding a specified project may be retrieved from external forum portals such as collaborative forums for programmers (e.g., www.stackoverflow.com), discussion forum, or other portals.

The analysis selector 216 is responsible for mapping project artifacts 205 a-205 d as inputs to one or more appropriate analysis engines, which are described in greater detail elsewhere herein. For example, artifacts that describe team composition and/or team member reputation may be mapped to a team analysis engine, such as team analysis engine 230 c in the depicted embodiment.

Analysis engines 230 are, in at least some embodiments, ‘pluggable’ components in the PMA system, meaning that particular analysis engines may be added/removed from the system depending on the specified project to be assessed. In certain embodiments, at least some of the analysis engines 230 may be trained to detect a relative degree to which a particular feature set is present in the specified project and output a weighted feature vector. For example, a sentiment analysis engine (such as sentiment analysis engine 230 a) takes as input a description of the issues reported in an issue tracking system associated with the specified project, and may output an indication as to whether there is positive or negative sentiment associated with the project. In one or more embodiments, each of the analysis engines 230 may additionally provide a confidence score regarding one or more feature vectors of its output.

In the depicted embodiment, analysis engines 230 include sentiment analysis engine 230 a; activity analysis engine 230 b; team analysis engine 230 c; bug analysis engine 230 d; usage analysis engine 230 e; dependency analysis engine 230 f; and feedback analysis engine 230 g. A brief description of each of these analysis engines with respect to at least the depicted embodiment is provided below.

Sentiment analysis engine 230 a utilizes natural-language processing to analyze the text associated with various artifacts and sources in order to evaluate one or more positive or negative sentiments regarding those artifacts and sources.

Activity analysis engine 230 b typically computes summary metrics regarding a level of project activity, such as may be manifested by a number of issues opened/closed, a number of code commits (i.e., set of related changes), a number of files changed; a number of project forks (i.e., copies of a source code repository) associated with the project; etc.

Team analysis engine 230 c generates one or more metrics characterizing an evolution of a team associated with a project, such as may be evidenced by the number of new team members in relation to a number of departed team members; experience levels and relevant expertise of a team; and the extent to which team members are “shared” by other teams and/or other projects.

Bug analysis engine 230 d produces metrics that inform whether changes to the associated project is considered to have stabilized over time. Such metrics may include a number of new features opened or closed; a degree to which bugs associated with the project have increased or decreased; a level of timeliness with which features associated with the project have been implemented; a level of timeliness with which bugs associated with the project have been fixed; etc.

Usage analysis engine 230 e produces metrics characterizing a degree to which a project is being utilized. Such metrics may include a number of forks associated with the project; a number of installations of the project; a number of deployments of the project; a number of transactions or API calls associated with the project; etc.

Dependency analysis engine 230 f determines other projects depending upon the current project to be analyzed. The maturity levels of dependent projects would “propagate up” and inform the maturity level of the current project.

Feedback analysis engine 230 g generates metrics characterizing user feedback regarding the current project, as manifested in bug reports, forum posts, etc. For example, feedback for a mature project would be relatively stable, and would contain relatively few bug reports and/or complaints regarding missing or unstable functions of the project.

In the depicted embodiment, the prediction engine 240 includes a machine learning model 242 and a machine learning rules engine 244. The prediction engine typically includes a training phase and a testing phase. During a training phase, the prediction engine receives already assessed data (i.e., projects previously assigned an assessed maturity rating) to provide a machine learning model 242. During the testing phase, an unlabeled project is classified according to the machine learning model to output the project's maturity assessment rating, along with (in at least some embodiments) a confidence score regarding that maturity assessment rating. As the prediction engine 240 receives additional information over time, the engine may continuously improve the model regarding particular features that may be more relevant for predicting the maturity of the project. One example of a machine learning model is neural network (or deep learning). In the depicted embodiment, the prediction engine 240 further includes a machine learning engine 244 that is based on rules, such as rules provided by one or more users associated the PMA system or developed by the machine learning model 242 based on historical input.

In one or more embodiments, the PMA system may consider additional domain knowledge that is relevant to the end user. The depicted embodiment further includes project domain analyzer 220, which is responsible for analyzing information about intellectual property and usage licenses, project source code, developer and project reputation, project type (e.g., a library as opposed to a service), lifecycle information, developer processes, etc.

As an example, if a software library developed by an organization reflects the core strategy of that organization, then the maturity of the project may receive a higher maturity assessment rating by the project domain analyzer 220 and, in turn, the PMA system. As another example, if an organization working on financial services publishes a software library related to financial technology services, the project domain analyzer 220 may use the reputation of the organization in an area to weight its feature vector(s) output to the prediction engine accordingly. Similarly, if a software project is developed using an obscure programming language that is hard to maintain and difficult to get developer resources, the maturity of the project may receive a lower maturity assessment rating and/or confidence level. As yet another example, if the PMA system is tasked with determining a maturity rating for a project specified by an organization which is working on mainframe computing systems, then software projects which are written in COBOL may receive a higher maturity rating, such as if the organization is known to possess the knowledge/expertise to maintain projects written in that particular programming language.

The following discussion describes activities of an embodiment of a PMA system in accordance with techniques described herein and an internal catalog containing approximately 800 projects from IBM Research. Such projects typically follow a maturity lifecycle consisting of stages described as Basic, Alpha, Beta and Commercial. The PMA system (and components thereof, such as prediction engine 240 in the embodiment depicted in FIG. 2) are typically trained using manually labeled asset maturity ratings from the internal catalog.

Typical projects from the internal catalog include “The catalog API” project. In order to evaluate a maturity rating for a project, a variety of URLs may be provided to the PMA system, with each provided URL corresponding to a particular artifact associated with the “The catalog API” project. A non-exclusive list of such artifacts may, for example, include a project summary and description; project issues (via an issue tracking system available at the corresponding provided URL); project feedback and associated comments (via a project forum available at the corresponding provided URL); and project source code. Specific URLs associated with such artifacts are input to the PMA system in order for the PMA system to evaluate a project maturity rating for the project.

A data sufficiency analysis is performed by data sufficiency analyzer 212, which indicates that dependency information regarding the project is missing. For purposes of this example, the data sufficiency engine may be configured using rules that check for the presence of data feeds for each of the analysis engines. In another embodiment, the data sufficiency analysis engine is also a trained machine learning model.

The data source retriever 214 then gathers dependency information about the asset using one or more domain policies. As one non-limiting example, a domain policy may specify to query one or more domain-specific software tools for such dependency information. Typically, a higher maturity rating of a specified project may be associated with a greater number of additional projects utilizing that specified project.

The analysis selector 216 maps each of the above artifacts into one or more of the multiple analysis engines 230. For example, asset feedback/issues/comments may be mapped as input to the activity analysis engine 230 b and bug analysis engine 230 d. For purposes of this example, the bug analysis engine 230 d outputs a feature vector with features such as a quantity of open (unsolved or unaddressed) errors, a mean time to resolve such errors, a quantity of such errors classified as or otherwise deemed critical, and a general user sentiment associated with resolved errors. Each of the analysis engines 230 outputs such a feature vector, which is in turn input to the prediction engine 240 to provide a project maturity assessment rating.

In this example, the project maturity assessment rating is provided (along with a confidence score regarding that assessment rating) to a user for validation. In addition, human feedback may, in certain embodiments, be utilized to continuously improve the learning components of the PMA system.

FIG. 3 depicts a process flow 300 for a PMA system in accordance with an embodiment of techniques described herein. The routine begins at block 305, in which the PMA system receives indications of a plurality of artifacts associated with an indicated project, such as if one or more users provide a uniform resource locator (URL) associated with one or more of the associated project artifacts. At block 310, the PMA system begins processing each of at least some of the plurality of artifacts associated with the indicated project.

In the depicted embodiment, processing each artifact includes determining at block 315 (such as via Data Sufficiency Analyzer 312 of FIG. 3) a data sufficiency level associated with each of one or more of the project artifacts. Processing continues at block 320 by identifying one or more of multiple analysis engines to utilize for analyzing the project artifact, and executing (at block 325) the identified analysis engines to generate a feature vector and/or other appropriate rating for the project artifact. As described in greater detail elsewhere herein, non-limiting examples of such analysis engines include the analysis engines 230 of FIG. 2.

At block 330, the routine determines whether all of the project artifacts associated with the indicated project have been analyzed using the analysis engines identified for each of those artifacts. If not, the routine returns to block 315 in order to begin processing the next project artifact.

Once the PMA system has analyzed all of the artifacts associated with the indicated project, the routine proceeds to block 335, in which the PMA system generates one or more weighted feature vectors for each of those project artifacts. At block 340, the PMA system provides a maturity rating for the indicated project based at least in part on the weighted feature vectors generated in block 335.

In block 390, the PMA system determines whether it is to continue, such as in response to receiving an explicit indication to terminate. If it determines to continue, the PMA system routine returns to block 305 to await further indications of additional projects and/or artifacts associated with those projects. Otherwise, the PMA system may end operations of the depicted and/or other routines as appropriate, as shown at block 395.

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed.
